Impacts Of Coyote Removal On Space Use By Greater Sage-Grouse, Elizabeth K. Orning, Julie K. Young
Impacts Of Coyote Removal On Space Use By Greater Sage-Grouse, Elizabeth K. Orning, Julie K. Young
Human–Wildlife Interactions
Greater sage-grouse (Centrocercus urophasianus) are in decline across western North America. Identification of management strategies to enhance populations, such as predator management, may be needed to reduce further declines, but unintentional effects associated with increased human activity should also be considered. We evaluated the effect of 3 levels of predator management effort on greater sage-grouse space use. Home range size, movement rate, seasonal movement timing, and inter-seasonal distances traveled were examined as behavioral responses relative to levels of coyote removal in Bighorn Basin, Wyoming. We observed larger home range sizes during brood-rearing but overall smaller annual core (25% …

Human–Wildlife Interactions
Greater sage-grouse (Centrocercus urophasianus; sage-grouse) is a sagebrushobligate species that has experienced species-wide declines in population density and distribution. Sage-grouse habitats support human-related needs including domestic livestock grazing, urban development, and energy extraction. The U.S. Fish and Wildlife Service identified energy extraction as a range-wide sage-grouse conservation threat. Mining has been of specific concern because of observed sage-grouse population declines and impaired habitat within close proximity to the activity. Mining may be particularly problematic for small, isolated sage-grouse populations. In southwestern Utah, proactive habitat improvements and predator management have been implemented to mitigate the potential effects of surface …
Impact Of Sagebrush Nutrients And Monoterpenes On Greater Sage-Grouse Vital Rates, Brian R. Wing, Terry A. Messmer
Impact Of Sagebrush Nutrients And Monoterpenes On Greater Sage-Grouse Vital Rates, Brian R. Wing, Terry A. Messmer
Human–Wildlife Interactions
Greater sage-grouse (Centrocercus urophasianus; sage-grouse) depend on sagebrush (Artemisia spp.) to complete its annual life cycle. The winter diet for sage-grouse consists almost entirely of sagebrush leaves, and individual birds may gain weight while foraging on sagebrush. Previous studies have reported higher crude protein and lower monoterpene concentrations in the sagebrush species selected as winter forage by sagegrouse. However, no studies have attempted to link female sage-grouse vital rates (i.e., nest initiation and success, egg fertility, clutch size, and adult survival) to crude protein or monoterpene concentrations of sagebrush plants browsed during pre-nesting periods. From March …
Influence Of Transmission Line Construction On Winter Sage-Grouse Habitat Use In Southern Utah, Erica P. Hansen, A. Cheyenne Stewart, S. Nicole Frey
Influence Of Transmission Line Construction On Winter Sage-Grouse Habitat Use In Southern Utah, Erica P. Hansen, A. Cheyenne Stewart, S. Nicole Frey
Human–Wildlife Interactions
The construction and operation of electric power transmission lines (“power lines”) and their associated infrastructure has been identified as a conservation threat to the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The conservation buff er zones recommended by state and federal agencies to avoid potential impacts on breeding populations diff er because information regarding the effects of power lines on sage-grouse is lacking. Little information is available regarding sage-grouse responses to power lines placed in winter habitat. Hence, we evaluated sage-grouse habitat use before and after construction of the Sigurd-Red Butte (SRB) 345-kilovolt (kV) transmission line in winter habitat. The …
Ecology Of Greater Sage-Grouse Populations Inhabiting The Northwestern Wyoming Basin, Casey J. Cardinal, Terry A. Messmer
Ecology Of Greater Sage-Grouse Populations Inhabiting The Northwestern Wyoming Basin, Casey J. Cardinal, Terry A. Messmer
Human–Wildlife Interactions
Range-wide population declines of greater sage-grouse (Centrocercus urophasianus; sage-grouse) have been largely attributed to habitat loss and fragmentation. However, the specific conservation threats affecting the ecology of sage-grouse populations may diff er by region. Although the status of the Bear Lake Plateau and Valley (BLPV) sagegrouse populations in the Wyoming Basin has been monitored using male lek counts since the 1960s, little was known about their ecology, seasonal movements, and habitat use patterns. From 2010–2012, we radio-marked 153 sage-grouse (59 females and 94 males) with very high frequency necklace-style radio-collars throughout the BLPV study area, which encompassed parts …
